CARGO BED COVER (CBC), TYPE IV, 5 T CARGO TRUCK, MTV, AND MTV TRAILER
Drilling the mounting holes in the vehicle bed
Drilling is made easier by starting with a smaller diameter drill bit.
Increase the drill bit diameter in steps until the required diameter is met.
Once the CBC has been removed from the vehicle bed to allow access to the hole positions marked
previously, Rivnut installation holes must be drilled at each of the 3/8 inch transfer punch locations (19
total), to their final size using a letter "Z" (.413 inch) diameter drill bit. Make sure that the drill bit is
postioned in the center of the punched mark.
Always apply anti-sieze lubricant to bolt and screw threads before
installation to prevent galling.
During the installation of blind rivet nuts (Rivnuts), the threads inside the
Rivnut can sometimes be damaged by the installation tool, and may
result in the the bolts and screws binding. If this occurs, run a 5/16-18
UNC tap (included with the mounting kit) into the threaded area. This will
clear and straighten the threads, making for easier and faster assembly.
Care should be taken using this method since the tap has the ability to
remove and/or cross thread existing threads. Be sure to work slowly and
deliberately when clearing the threads.
When all holes are drilled, install Rivnuts in each of the 19 installation holes using the hand operated
Rivnut installation tool (1), hex (allen) wrench (2) (included with installation tool), and 3/4 inch (or 1 1/16
inch depending on header tool used) wrench (3) (adjustable, fixed, or box end ratchet type).
Before using the installation tool, inspect the condition of the jackscrew
threads before use. If the tool has been used previously, the jackscrew
threads may require a few drops of a light machine oil. If this is the initial
use of the tool, no additional lubrication will be required.
To install a Rivnut, thread the Rivnut fastener (4) onto the threaded end (5) of the installation tool (1)
included with the mounting kit. Be sure that the end of the installation tool is tight against the head of the
With the Rivnut (4) installed on the installation tool (1), insert the Rivnut into the hole (6) previously drilled
in the vehicle bed (7).
